The information also states that there is a 15% chance of experiencing both side effects What is the probability of experiencing only dizziness? 0.35 0.20 O 0.12 0.05 none of these

Explanation / Answer

Question 5 :

We have given that

P(D) = 0.20 P(H)= 0.40 ,P(D and H)=0.15 and we have to find P(D or H) =?

P(AB) = P(A) + P(B) - P(AB) = 0.20 +0.40 -0.15 = 0.60- 0.15 =0.45

So correct answer is 0.45

Question 6:

P( ONLY D) = P(D) -P(D and H) = 0.20 -0.15 = 0.05
